I am not sure, whether I understand your question correctly. If you intend to make a PCA from multidimensional data and then plot the 2 or 3 most significant dimensions, then you need to do these steps:

Thomas,
I am sorry that I did not pose my question clearly. The PCA plots (PC1 vs PC2, for example) generated as per your instructions are the scores, describing the relations among the observations (samples, rows); I am trying to see if the corresponding loadings plots describing the relationships among the variables (columns) can be displayed as well. Thank you.

Kellie,
thank you for clarifying. Currently the linear contribution factors (loadings) of the original dimensions are just used internally. One could think of adding a button that allows to copy them as a new table into the clipboard. A paste operation would then create a new DataWarrior file allowing to depict the contributions.
